The present invention relates to an improved agitator or mixerfitted With mobile deflecting baflies.

According to this invention, a number of deflecting bafiiespre'ferably mutually connected, and destined to bring about the mixing of several liquid or viscous materials or of one or more liquid or viscous materials Withsolids, the materials to be admixed being set in circular motion Within a tank or other suitable vessel-are provided With counter-Weights capable of keeping the bat fies at the surface of the liquid contained in the vessel, independentlyoit the level or the state of movement of the liquid. By means of the counter-Weights, the battles can be made to immerse in the liquid more or less deeply, at Will. This equilibrated suspension of the deflecting baflles presents several advantages,

notablythe following:

(a) The bafiles automatically adapt themselves to all changes of the level of the materials to be mixed; I

(b) The live force of the materials to be mixed which are. set in rotation by any appropriate process, is not in any Way utilized to raise the baffles tothe surface of the materials or to keep them there. This means a considerable saving of motive power.

(0) By increasing or diminishing the coun tier-weights in case pulleys are used, or by a simple displacement of the counter iveights along their levers, the battles are easily adapted to any liquid.

The accompanying drawings represent one mode of realization of the present invention.

I claim: V

1. In a mixer having a vesselfor containfor rotating the same, the combination of de-.

fleeting battles vertically movable in said vessel and means for exertingupon said bafiles a continuous upward torce independent of'the state of rest or motion of the material in the vessel. 9 H

3. A mixer according to claim 2 wherein the upward force exerted by said last men-. tioned means is less than the Weight of the baflles, but greater than the differencebetween the Weight ofthe baflles and the Weight of the material displaced by the immersion of said battles.v a v FELIX EPSTEIN: I
